1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 10 NIK 100 PURE NICKEL ELECTRODE FOR FULLY MACHINABLE, CRACK- RESISTING WELDS ON ALL GRADES OF CAST IRON DATA SHEET NO. 144 SPECIFICATION AWS A5.15 EN ISO 1071 JIS Z 3252 CLASSIFICATION ENi-CI E CNi-C13 DFC Ni PRODUCT DESCRIPTION The design emphasis of the chemically basic flux assures the metallurgical integrity of the weld metal. The high graphite content of the flux is expelled from the molten metal, compensating for the compression welding stresses thus preventing weld metal cracking. The core wire is pure nickel. WELDING FEATURES OF THE ELECTRODE The arc is stable both AC and DC, but is very soft, thus minimising dilution. Weld beads are smooth, bright and evenly rippled. The slag is fairly fluid but relatively quick freezing, thus allowing smooth blends when edges are involved. The slag is readily controlable, thus making positional welding very easy, plus the slag is easily detachable. APPLICATIONS AND MATERIALS TO BE WELDED Successful welding of cast irons is dependant on low strength weld metal and controlled heat input welding procedures. Both characteristics are assured by the use of NIK 100. NIK 100 may be used for all standard grades of grey cast iron and malleable cast irons. Typical applications include repairs to engine blocks and heads, gear housings, machine bases, as well as repairs to used castings. Is also used to rectify casting defects on new castings.
